To all fwlt'om t may concern: Be 'it known that il, JEAN MAZUEL, citieen .of the French-Republic, residing at 8.1

Rue St. Dominique, Paris, France,r haveinand useful Improvements 1n vented riew ,"This invention harsf'or its objectfto provide an impe-(Wedl stop cock for controlling liquid- -fuel te' the motor. of a 'il The improved stop i cock comprises a pl c?v4 rality yofcock plugs located side by side in unitary member or cockcasing in such a manner that the 'bore of the cock can be opened onl bina'ftion, and only by turning veach'one of the separate cock-plugs' tov theorie l'particular position which alone permitsf-free passage through ithat particular' plug(l 'l`hejinr1-` 'thus constitutes la safetydef conven-ientlyand rapidly changing the comf bination, and it thus :provides anfelfcctual means for preventing the theft of mot-or vehicles.

rThe bore of .the improved cock, that is to say the passage between the inlet and outlet is madev of zigzag shape having the peculiarity that each cock plug contains a substantially Z-shaped lportion of said bore.

These disks orrings are designedI to Jform a number or word doneQeii'ects the opening et the cock. -This number or word vwhich may be changed by the owner or'the holder of the safety cock, will then appear, for insta-nce on the side of the carbureter ot a noter vehicle. i y

VIn these drawings-: -Figure'l is a ylongitudinal vsection of `the improved cock `when open. Fig, 2 is a plan thereof.v Fig; 3 is a perspective View of one of the numbered l blocks used in carrying outv this invention.

."As shown the improved cock comprises a rectilinear member or casing A in which are :.itted so as to be capable of rotation a pluralityo'f non-contiguous cock plugs l, 2,

4 which lie side-byside in alim-ement und are held n place in the usual manner. The

cock bore is formed partly in the cock cas?l ing and partly in the several cock plugs, and has the shape of a broken or zig-zag linea 1, l), 2', c, 3', d, 4, e, whereof the ortions 1, 2, 3', et', belong respectively to the cock plugs 1, 2, 3, 4, and are substan- I'-- tia llyof Z-shape or'as shown in dotted lines, .-so that each cock plug-can be turned through a complete revolutionfrom its open position in order to return into said lopen position. Each'of said c ock plugs has at i-tsuppcl' part a head 1,.2, 3, 4 of square or polygonal section.l upon which are respec tively threaded or fitted nut-like blocks 5,'

5, .5, 5 of mre'or less prismatic shape The top 'face of each block is divided intoy (for instance six) panels each having anumeral, letter, color or any other suitable mark or sign in a-suitable order of succesA sion. These blocks are held in position by means of screws screwing intor the heads oi the cock plugs or in any other'suitable manner.

In setting each' block 5, etc., in position it is an easy matterto bring yany desired oney of its numerals, letters, color or signs opposite the line X-X of the cock casing (Fig. 2) which is used as a datum line. This setting of the blocks'is done when all the cock plugs are in ltheir openV positions (Figal), and the number constituted by the series of 'numerals thereby made 'to face'tlie datum line i Xis the number which must be reproduced in order to. open the cock to allow a supply of the liquid'fuel to pass through the cock.

l'The'n the driver leaves his vehicle, he

need only rotate one or more of the several cock plugs to ar greater orderto shut cti the su also jumble up the nnrn 'ply of fuel and er to which the or lessl extent in wholevseries of cock plugs -iinust ibe set order to resto-re the supply of. fuel. Under these conditions no person other-than the driver can reopen the cock except by vvery protracted trials.

It is in the power ofthe driver to change the. combination number for opening the cock as many times as he" likes in the/course of the day. For this purpose he has merely to dismount the number blocks and to change their order in t-he series.`` Further, the construction of the bore a, b, c, (l, e in a broken or zig-zag line increases the security by preventing the insertion of a metal wire which might be employed for the purpose of .ascertaining more or less quickly the open positions of the plugs.

The improved cock maybe made of any form and size and with any number of plugs. It may be provided on onev side with a screw connector 6 for connection to the liquid fuel su' ply pipe, and on the other side with a neck g for mounting on the carbureter. Theconnector 6 ,may contain a wire gauze strainer for keeping out any impurities that mightotherwise choke the bore of the cock.

In a modification the improved cock may comprise only the plugs 2, 3 and 4, the plug 1 being omitted, and its portion 1 of the bore being made to continue directly into the cock casing A. This modification while cheapening the manufacture does not lessen the degree of security of the improved cock.

1. In a stop cock, the combination with a unitary cock casing, of a plurality of noncontiguous cock plugs, a common borel controlled by saidr cock plugs, a common datum on the cock casing, and a plurality of signs on each of said cock plugs of which one sign is selected by. its relation to said datum to denote the open position of its cock plug said signs constituting a series combination which can be broken up by rotating said cock plugs out of their open positions whereby in order to open said cock it is necessary to rotate cach of said cock plugs into a po-` sition inwhich the series of signs on said cock plugs reproduce in their relation' to said datum the combination which denotes that all the cock plugs and therefore the stop cock is open.

2. In a stop cock, the-combination with a unitary cock casing, of a plurality of non- 5 contiguous cock plugs,ya common 'bore con-v trolled by said cock plugs, a common datum on the cock casing, a member revolubly adjustable on theprojecting end' of each' cf said `cock plugs and bearing a plurality of characters, and means for fixing reach of said members in the position on its cock `plugin which any selected character on that particular member denotesin its relation to said common datum that its cock plugv is open.

3. Il1 astop cock, the combination with a unitary and longitudinally-extending cock casing of a plurality of non-contiguous cock plugs and a common bore compo-sed of Z- shaped portions in said cock plugs 'and straight portions in the cock casing, a common datum line on the cock casing, a member revolubly adjustable on the projecting end of each of said cock plugs and bearing a plurality of characters, and means for fixing each of said members in the position on its cock plug in which any selected char-` acter on said member denotes in its relation to said common datum that its cock plug is open, the Z-shaped portions of the common bore preventing the insertion of a Wire through same for the purpose of. ascertaining the open positions of said cock plugs.

4t.- A combination stop-cock, consisting of a unitary member having a continuous passageway exten-ding longitudinally therethrough 'and having also a plurality of transverse valve-seats intersecting. said `passageway, and a rotary plug-valve tted into each seat and having a stem at its outer end and having also a transverse opening adapted to register with said passageway, and a radially-adjustable block secured upon each stem and presenting a plurality of characters or symbols, the correspondingly-located characters or symbols on the respective blocks beingin a straight line.

In testimony whereof I have signed my name tothis specification in the presence of two subscribing witnesses. y
